did you write the sentence in english , then want a translation to chinese? strange...

Corrected English: i learned (that) i had not been looking at a person as a whole person,and (was) not being open to differences. my chinese is not good but maybe you can say: 那時，我發現我不從整體上看別人 （怎麼講？），我也不樂意接受［差異／意見？ 英句不清楚］ this should give you some idea as to the english meaning. as a whole = take everything into consideration, instead of focusing on only some part being open to = be willing to consider
